The role of serotonin as a mediator and stress hormone and its function in vessel tonus regulation is proved. The aim of the work is to study the concentration of serotonin in blood in patients with vestibular disturbances before and after vestibular provocation and in patients with tinnitus. The study was performed on 134 persons distributed among three groups: group I, 35 patients with vestib...

The present study was conducted to investigate the relationship between the anti-stress and hepato-protective effects of Schisandra Lignans Extract (SLE) on stress-induced liver damage. Seven weeks old male mice were fixed in a restraint tube for 18 h to induce liver damage. SLE was orally administered to animals for 5 days at dosages of 100 and 200 mg/kg/day before exposed to restraint stress....

Deinococcus radiodurans is extremely resistant to various genotoxic conditions and chemicals. In this study, we characterized the effect of a sublethal concentration (100 microM) of cadmium (Cd) on D. radiodurans using a whole-genome DNA microarray. Time-course global gene expression profiling showed that 1,505 genes out of 3,116 total ORFs were differentially expressed more than 2-fold in resp...

Psychological stress has multiple physiologic and clinical impacts on skin such as inflammation, itching, impair barrier function, provoking discomfort that can amplify psychological stress.
